Quantum Theory of Continuous Observations Some Significant Examples

Abstract

Ordinary Quantum Mechanics has to do with an idealized situation in which a system is prepared in a given state at an initial time t0, it is left to evolve freely for some time and it is submitted to some kind of measurement at a single final time t1 or at certain well separated subsequent times t1, t2,... In any case the single process is considered as pratically istantaneous.
